This library is a collection of pseudo random number generators.

While Common Lisp does provide a RANDOM function, it does not allow the user to pass an explicit SEED, nor to portably exchange the random state between implementations. This can be a headache in cases like games, where a controlled seeding process can be very useful.

For both curiosity and convenience, this library offers multiple algorithms to generate random numbers, as well as a bunch of generally useful methods to produce desired ranges.

This is a Common Lisp library to enable simple message pipelines.

CL-FastCGI is a generic version of SB-FastCGI, targeting to run on mostly Common Lisp implementation.

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.

This library provides a macroexpand-all function that calls the implementation specific equivalent.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

This implements encoding and decoding of Punycode strings, specified in RFC 3492 and used for unicode characters in domain names.

This package defines a simple extensible protocol for computing a guess using advisors.

This package provides a Common Lisp system helping in scripting, it uses uiop:run-program as a backend.

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

Chemboy is a Common Lisp program for doing basic chemistry calculations. This package provides the text-based interface for Chemboy.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

This package provide a Common Lisp library for .zip-file reading and writing.

This package provides functions for base32 encoding and decoding as defined in RFC4648.

This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

Quickproject provides a quick way to make a Common Lisp project. After creating a project, it extends the ASDF registry so the project may be immediately loaded.

This package provides a Common Lisp environment for declarative and generative algorithmic composition.

FLARE is a library designed to allow quick and precise particle effect creations. It does not concern itself with displaying and only with the management and movement of particles. As such, it can easily be integrated into any existing or future application.

This package provides a client for SMTP.

This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW
